Hart Manufacturing makes three products. Each product requires manufacturing operations in three departments: A, B, and C. The labor-hour requirements, by department, are as follows. Department Product 1 Product 2 Product 3 3.00 Max A s.t. B C Department A Department B Department C 1.50 P1, P2, P3 20 2.00 0.25 During the next production period, the labor-hours available are 450 in department A, 350 in department B, and 50 in department C. The profit contributions per unit are $27 for product 1, $27 for product 2, and $32 for product 3. (a) Formulate a linear programming model for maximizing total profit contribution.
